The Norwesco 100 Gallon 15 Degree Cone Bottom Tank (SKU N-41461) is a full-drain polyethylene vessel built for batching, mixing, and dispensing where you want every last gallon out the bottom. It stands 63 inches tall on a 23 x 23 inch footprint, holds 100 gallons, and carries a 1.5 specific gravity rating, meaning it is engineered to hold contents up to 1.5 times the weight of water without compromising the wall. The 15 degree cone slope drains by gravity while still letting the tank sit in a relatively compact stand, which is why it stays a popular choice among people searching for a 100 gallon cone bottom tank from Norwesco.
Will it work for your application?
Match the contents to the 1.5 SG rating first. With water, a full 100 gallons weighs 834 lb; at the tank's maximum rated 1.5 specific gravity, supported contents reach 1,251 lb. Use those numbers when you size the cone stand and the slab or skid beneath it. That 1,251 lb sits on a small 23 x 23 inch base, roughly 3.7 square feet, so the load is concentrated and the surface under it has to carry the 1.5-SG worst case without flexing, not just the water weight. At 63 inches tall when full the assembly is also top-heavy, so rate and anchor the cone stand accordingly. This listing does not include a pre-installed bottom fitting; size the discharge outlet from the technical drawing on this page and add the fitting and gasket package separately. For help dialing in volume against your batch size, run the Tank Sizing Calculator or read the Tank Sizing Guide.
Chemical compatibility
This tank is molded from high-density linear polyethylene and carries a 1.5 specific gravity rating. Because resin choice drives chemical resistance, confirm with us whether your tank is HDLPE versus XLPE (crosslinked) before any chemical service, since the two resins do not share the same resistance profile. Compatibility below is keyed to that 1.5 SG rating and to concentration. Always verify against the OEM chemical-resistance chart, which is concentration- and temperature-specific, for your exact fluid and operating temperature.
At the 1.5 SG rating, this tank is rated for chemicals including Acetic Acid at 60% (PP or PVC fittings, EPDM gaskets), Aluminum Sulfate at 50%, Calcium Chloride at 40%, DEF at 32.5% (316 stainless fittings, EPDM gaskets), Ferrous Sulfate at 20%, Magnesium Chloride at 30%, Sodium Carbonate at 30%, Urea Solution at 50% (PP or PVC fittings, EPDM gaskets), and Ozonated Water up to 10 PPM. Unless noted, specify PVC fittings with EPDM gaskets. The exact fitting and gasket spec per chemical is listed on each chemical page and in the Chemical Compatibility Database.
Chemicals that need a higher-SG tank
Some fluids exceed what a 1.5 SG tank should hold and require the 1.9 specific gravity version of this tank instead. The single most common and costly mistake on a cone bottom tank is matching the chemical to capacity but ignoring specific gravity. Do not put these in this tank: Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Hydrogen Peroxide, Peracetic Acid, Phosphoric Acid, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite (chlorine bleach), Sodium Thiosulfate, Sulfuric Acid, and Zinc Orthophosphate. Several of these also escalate the gasket spec: hydrochloric, hydrofluoric, hydrogen peroxide, phosphoric, sulfuric, and sodium hypochlorite call for Viton, and peracetic acid calls for Aflas, rather than EPDM. So confirm both the SG tank and the elastomer before you order; call 866-418-1777 and we will spec the 1.9 SG tank and the right fitting package for your fluid.
